Tony Romo tied for the league lead with 19 interceptions last season. He threw 14 of them in four games.
The Cowboys went 0-4 in those games, and they're 4-15 overall in games that Romo has thrown multiple picks.
Every quarterback throws interceptions; the key for Romo is limiting his mistakes. Turnovers are the most important stat in the game because teams that win the turnover battle win the vast majority of the games.
It will help if the Cowboys run the ball better and start games faster so they're not playing from behind so much. But it's up to Romo to protect the ball since he has it in his hands most of the time.
